[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a belt conveyor frame, including a base plate 1, support legs 2 are installed at the four corners of the bottom end of the base plate 1, a moving mechanism is provided at the bottom end of the base plate 1, a roller 3 is installed at the bottom end of the moving mechanism, a lifting mechanism is provided at the top end of the base plate 1, a mounting plate 4 is installed at the top end of the lifting mechanism, a mounting frame 5 is installed above the mounting plate 4, a mounting block 6 is installed at the top end of the mounting frame 5, an upper roller 7 is installed on the inner side of the mounting block 6, a side plate 8 is installed below the inner side of the mounting frame 5, and a lower roller 9 is installed on the inner side of the side plate 8.

[0020] The moving mechanism includes an installation cavity 14, an articulated block 15, a connecting rod 16 and a transmission structure. The installation cavity 14 is installed at the bottom end of the base plate 1. The articulated block 15 is installed on one side of the installation cavity 14. The connecting rod 16 is hingedly installed inside the articulated block 15. The bottom end of the connecting rod 16 is connected to the top of the roller 3. The transmission structure includes a servo motor 17, a threaded rod 18, a threaded sleeve 19, an articulated rod 20 and a limiting structure. The servo motor 17 is installed on one side of the installation cavity 14. The threaded rod 18 is installed below the inside of the installation cavity 14. The output end of the servo motor 17 is connected to one end of the threaded rod 18. The outer side wall of the threaded rod 18 is provided with a threaded sleeve 19. The bottom end of the threaded sleeve 19 is hinged with an articulated rod 20. One end of the articulated rod 20 is hinged to one side of the connecting rod 16. Then, when in use, the servo motor 17 is started to drive the threaded rod 18 to rotate. Therefore, under the limit of the limit rod 21 and the limit sleeve 22, the threaded rod 18 is used to drive the threaded sleeve 19 to move, thereby driving the hinged rod 20 to move, and then driving the connecting rod 16 to move, driving the roller 3 to extend, so that the roller 3 contacts the ground. At this time, the staff can push the frame to adjust the frame to an appropriate position, and then start the servo motor 17 to reverse it, drive the roller 3 to move, and slowly retract the roller 3 so that the supporting legs 2 contact the ground. The frame is supported, and the roller 3 can be driven to be conveniently retracted and extended, making the frame more convenient and efficient when moving, transporting or transferring. At the same time, after the roller 3 is retracted, the frame is also relatively stable when in use, thereby greatly improving the convenience of the frame when in use.

[0021] The limiting structure includes a limiting rod 21 and a limiting sleeve 22. The limiting rod 21 is installed above the inside of the installation cavity 14. The limiting sleeve 22 is arranged on the outer wall of the limiting rod 21. The bottom end of the limiting sleeve 22 is connected to the top end of the threaded sleeve 19. The cross section of the limiting rod 21 is smaller than the cross section of the limiting sleeve 22. A sliding structure is formed between the limiting rod 21 and the limiting sleeve 22. When in use, the threaded sleeve 19 can be limited when moving by the cooperation between the limiting rod 21 and the limiting sleeve 22, so that the threaded sleeve 19 is more stable when moving.

[0022] The lifting mechanism includes a guide hole 10, a guide rod 11, a guide plate 12 and a cylinder 13. The guide hole 10 is opened through the interior of the mounting plate 4. The guide rod 11 is arranged through the interior of the guide hole 10. The bottom end of the guide rod 11 is connected to the top end of the base plate 1. The top end of the guide rod 11 is installed with a guide plate 12. The cylinder 13 is installed in the middle position of the top end of the base plate 1. The top end of the cylinder 13 is connected to the bottom end of the mounting plate 4. When in use, the cylinder 13 is started, and the mounting plate 4 and the mounting frame 5 are adjusted to an appropriate height under the limitation of the guide hole 10 and the guide rod 11, so that the frame can be used in conjunction with different machines, thereby greatly improving the versatility of the frame when in use.

[0023] A plurality of guide rods 11 are arranged inside the mounting plate 4, and the plurality of guide rods 11 are symmetrically distributed inside the mounting plate 4. When in use, the mounting plate 4 can be guided when moving by utilizing the cooperation between the guide rods 11 and the guide holes 10, so that the mounting plate 4 is more stable when moving.

[0024] Working principle: the staff first starts the servo motor 17 to drive the threaded rod 18 to rotate, so under the limit of the limit rod 21 and the limit sleeve 22, the threaded rod 18 is used to drive the threaded sleeve 19 to move, and then the hinged rod 20 is driven to move, and then the connecting rod 16 is driven to move, and the roller 3 is driven to extend, so that the roller 3 contacts the ground. At this time, the staff can push the frame and adjust the frame to an appropriate position, and then start the servo motor 17 to reverse it, drive the roller 3 to move, and slowly retract the roller 3 so that the supporting leg 2 contacts the ground, and the frame is supported. Then start the cylinder 13, and under the limit of the guide hole 10 and the guide rod 11, adjust the mounting plate 4 and the mounting frame 5 to an appropriate height so that the frame can be used in conjunction with different machines.
